EPECIPICATION forming part of Letters Application filed May 10, 1886.

To all whom it may concern:

Beit known that I, ABLE Gnovn HEATH, of the city, county, and State ofNew York, have invented certain new and useful Improvements inKerosene'Lamps without Chimneys 5 and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same.

My invention relates to that class of lamps in which a fan operated byclock-work supplies a constant current of fresh air to the burner,thereby dispensing with a chimney.

The invention consists in the construction and combination of partshereinafter set forth, and specified in the claims annexed to thisspecification.

By reference to the drawing forming part of this specification, it willbe seen that the figure represents a side sectional view of my improvedlamp.

A represents the glass oil-reservoir surrounded with the outer casing,13, leaving an air-space, C, between them.

D is the lower portion of the lamp, which contains the central air-tube,fan, and devices for driving the fan.

E is the central metal tube, preferably of brass tubing, affixed to thesides of the lamp by brackets F.

G is the fan, placed near the top inside portion of the centralair-tube, E. It revolves the spindle H, which is carried by the bracket1 and center cross-piece, J. The lower part of the said spindle isformed with a worm, and a wormwheel,K, attached to thehorizontal shaftL, is made to engage with it, and so revolve it with the fan. Thewheelanovement for driving the fan is placed outside of the said tube E,and inside of the bracket-plate M, which is secured to the said tube E,and, in connection with the wall of the tube E, gives bearing to thespindles L N O P,with their pinions and movementwheels; but upon which Ido not make any claim, as they are the usual clock-movement.

Q is the spring placed on the shaft P, and made to be easily wound up bythe key R, on the outside of the lamp,for running the wheel movement andfan.

Patent No. 359,968, dated March 22,1857.

Serial No. 201,184. (No model.)

S are openings in the base of the lamp to admit air to the central tube,E, and thence through the fan to the spaces 0 0 up to the burner T.

U is a stop device employed to engage the worm on the spindle H, and so,if desired, stop the fan and wheel-movement when the lamp is notburning.

The operation of the lamp may be described as follows: It is firstsupplied with oil and the wick properly trimmed. wound up by means ofthe key It, which sets the wheels in motion to drive the fan G, which,as it revolves rapidly, draws upthe air through the central tube, E,from the openings S at the base, and causes a continuous upward currentof freshair through the spaces 0, to supply the burner with oxygenwithout the use of a globe or chimney. The lamp will thus give out abright white flame without smoke or odor, and also be cool, safe,healthy, and non-explosive; and the movement is calculated to run forabout twenty-four hours after each full winding up. It will further beobserved that when a round wick and burner are used the central tube, E,will be connected to the burner by means of an additional tube, V,through the oilreservoir A, as shown by dotted lines.

The upper part of the bracket-plate M covers the clock mechanismsufficiently to prevent any danger of oil, soot, or charred wick fallinginto the gearing, and thereby clogging its movements.

It will be observed that the lamp is so constructed that all its partscan be readily seen and reached for repairs and cleaning without takingit all to pieces.

Having thus described my device and its advantages, what I claim as myinvention, and desire to secure by Letters Patent, is-

1. The combination, with the central airtube, E, a fan, G, located insaid tube, and a clock-work mechanism exterior to the tube for operatingsaid fan, of a bracketplate, M, having its upper part located above saidclockwork mechanism to protect it from oil and soot, substantially asdescribed.
